Display Response Times

ℹ

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.

↔ Response Time Black to White

29 ms ... rise ↗ and fall ↘ combined

↗ 18 ms rise

↘ 11 ms fall

The screen shows relatively slow response rates in our tests and may be too slow for gamers.In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 67 % of all devices are better.This means that the measured response time is similar to the average of all tested devices (26.7 ms).

↔ Response Time 50% Grey to 80% Grey

42 ms ... rise ↗ and fall ↘ combined

↗ 20 ms rise

↘ 22 ms fall

The screen shows slow response rates in our tests and will be unsatisfactory for gamers.In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 52 % of all devices are better.This means that the measured response time is similar to the average of all tested devices (42.8 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

ℹ

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.

Screen flickering / PWM detected

21000 Hz

The display backlight flickers at 21000 Hz (Likely utilizing PWM) .

The frequency of 21000 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 57 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 6272 (minimum: 43 - maximum: 142900) Hz was measured.
